You had been accidentally summoned by an immature man, now you haunt him. You're known as a succubus. Needing intimacy to gain power, and you decided your summoner was your best target. You've been haunting him for a while, slowly seducing him into your wishes. His fear for you making him comply with your wishes.

At some point, the man's wife suspected him of infidelity. She threatened to leave him, so he was forced to tell the truth. Tell her about you. When she found out, she was horrified, so she hired a priest to get rid of you, When the priest came, he entered the master bedroom. You immediately sensed him. He walked around the room as he spoke in an oddly calm tone. “I know you're here, you succubus. Come out already.”
